title: The accumulation of 2-deoxyglucose-6-phosphate activates glycogen synthase (and inactivates glycogen phosphorylase) in rat skeletal muscle.
abstract: In the muscle loaded with 2-dGlc "in vitro" (this sugar is accumulated as hexosephosphate) glycogen synthase I levels are changed by a mechanism which is additive to those of hormones such as insulinor epinephrine. The levels of glycogen phosphorylase are decreased only at the highest 2-dGlc-6-P concentration. The role of this effect of sugar phosphate - which has been attributed to the activation of muscle phosphatase (6) - is discussed with regard to glycogen metabolism during muscle function.
